The Hofburg was built on a site once occupied by the fortifications and towers of the medieval city. In the fourteenth century, when Innsbruck was ruled by the
House of Gorizia, the city's
defensive walls included a section located where the Hofburg main façade stands today on Rennweg. Three structural elements of these early fortifications were retained and integrated into the palace: the South Roundel with its Hofgasse-Rennweg passageway on the eastern side of the palace was once called the Rumer Gate or Saggen Gate or Heraldic Tower, the North Roundel on the northeastern side was once a round tower, and the Corner Cabinet museum room was once a rectangular defensive tower. The town wall ran from the Rumer Gate to the round tower and continued west the rectangular tower, which can still be seen in the Hofburg façade as an irregularly projecting corner block. In 1406, Leopold's brother
Frederick IV, Duke of Austria (called
Frederick with the Empty Pockets) became ruler of Tyrol. Frederick moved the seat of rule from
Meran in present-day South Tyrol to Innsbruck, and constructed his New Residence, the building with the
Goldenes Dachl west of the Hofburg area. For Maria Theresa, the Hofburg took on greater importance "as a memorial site and representational building" to honor her husband. Per the empress's instructions, the anteroom where Francis died was converted into the Hofburg Chapel in 1766. The east wing was redesigned to accommodate the newly founded Noblewomen's Collegiate Foundation. New ceilings were installed, court building director Constantin Johann Walter was named creative planner, and in 1767 Maria Theresa placed her court architect
Nikolaus Pacassi—responsible for converting Schönbrunn Palace into a residential palace in Rococo style—in charge of the design and appearance of the main façade on Rennweg. After the roof framework was modified in 1774, the Giants' Hall ceiling fresco was executed by
Franz Anton Maulbertsch, the master of Austrian Rococo, between 1775 and 1776. The result of this extended renovation project under Maria Theresa is the Hofburg we see today. During the
Napoleonic Wars, after the Habsburgs ceded Tyrol to Napoleon's
Bavarian allies in 1805, the Hofburg became a residence of King
Maximilian I Joseph of Bavaria (1756–1825). In 1809, the South Tyrolean innkeeper
Andreas Hofer led an
uprising against the occupying Bavarian administration, and following the successful
Third Battle of Bergisel on 13 August 1809, Hofer moved into the Hofburg for two months, serving as the leader of Tyrol. After the
Congress of Vienna, Tyrol was returned to
Austria. In 1858, the last major reorganisation of the imperial apartments took place following the model of Schönbrunn Palace. Vienna court sculptor August La Vigne was commissioned to design the residential area in the Rococo style. Many of the furnishing added at that time are still in the imperial rooms today. During the course of his long reign, Emperor
Franz Joseph stayed at the Hofburg in Innsbruck on numerous occasions.
Empress Elisabeth of Austria, however, stayed overnight at the Hofburg only once, on 14–15 October 1871. Other Habsburg archdukes, Franz Josef's uncle
Ferdinand Karl (1818–1874), cousin
Eugen (1863–1954), and nephew Heinrich Ferdinand (1878–1969) stayed for longer periods of time at the Hofburg imperial apartments during the late nineteenth and early twentieth century. ==Imperial Apartments==
